One
end of the cable has an 8 pin mini-DIN plug which connects to the Data
socket on the radio. The other end has a USB plug which connects to the
PC's USB port. The
cable contains a USB to serial converter, so the radio appears as a COM
port on the PC. Length approx 1m/3ft 3ins.

This cable uses the highly regarded FTDI FT232RL chip which works with all these operating systems:

Windows 10

Windows 8 and 8.1

Windows 7

Windows Server 2008

Windows Vista

Windows Server 2003

Windows XP

Windows ME

Windows 98

Linux

Mac OS X

Mac OS 9

Mac OS 8

Windows CE.NET (Version 4.2 and greater)

Android

32 and 64 bit operating systems are both supported.

The FTDI chip is the only one that will work with the FTM-350 as the programming software uses an unusual baud rate that most USB to serial chips cannot generate.

Drivers and installation instructions on CD included. Latest drivers are also available from FTDI here.Driver installation guides are here.
